Import Tips
• Include AREMA or equivalent certification proving head-hardening heat treatment to justify 7302.10.1055 rate
• Ensure no fish-plating or drilling; unfinished rails qualify, but assembled track sections may shift to 7302.90
• Document import for track construction end-use to prevent dual-use scrutiny under anti-dumping measures
